Miramar Resources Doubles Gold Exploration Target at Gidji JV Project in WA
Miramar Resources has substantially augmented the prospective gold reserves at its Gidji Joint Venture Project. The exploration target in Western Australia has seen a twofold increase, building upon rigorous drilling assessments. This expansion underscores the project's burgeoning potential, particularly with an eye towards establishing a definitive mineral resource estimate.
Miramar Resources Bolsters Gold Outlook at Gidji Joint Venture
On Monday, June 29, 2026, Miramar Resources, a prominent player in the mining sector, announced a significant uplift in its gold exploration ambitions for the Gidji Joint Venture Project. This pivotal site, strategically positioned approximately 15 kilometers north of Kalgoorlie-Boulder in Western Australia, now boasts a gold exploration target twice its previous estimation. The updated projections stem from a comprehensive analysis of recent drilling campaigns conducted across key prospects such as Marylebone, Blackfriars, Powerline, Highway, and Railway.
The enhanced target is underpinned by an extensive data set, incorporating findings from 939 aircore drill holes, spanning a total depth of 53,362 meters; 26 reverse circulation (RC) holes, reaching 4,007 meters; and a single diamond drill hole extending 190.75 meters. Furthermore, historical drilling records were meticulously integrated into the assessment. It is noteworthy that the current estimation consciously excludes certain areas, including 8 Mile, Boorara North, Lake, and Claypan, owing to limited recent drilling activities in those locales.
Drilling efforts maintained an average spacing of 100m by 50m, though this extended to 400m by 100m in specific zones. The aircore drilling depths exhibited a range from 11 meters to 108 meters, averaging approximately 56 meters. In a move to refine data accuracy, Miramar modified its sampling protocols from August 2021, aiming to minimize the inclusion of overlying paleochannel sediments.
Looking ahead, Miramar identifies substantial opportunities for discovering additional gold mineralization. This includes pursuing deeper drilling into the primary bedrock structures and exploring regions beyond the currently defined paleochannel. The company's future plans encompass engaging a resource geologist to ascertain Joint Ore Reserves Committee-compliant mineral resources and preparing a detailed mineralization report, laying the groundwork for a prospective mining lease application.
Miramar's managing director, Marion Bush, expressed confidence in these developments, stating that the updated estimate, derived from actual drilling and assay data, has not only doubled the gold exploration target at Gidji but also pinpointed further potential in areas with minimal or no prior deep drilling. She conveyed the company's belief in the strong likelihood of a significant maiden mineral resource estimate and confirmed ongoing collaboration with resource geologists to review the extensive drilling data.
The Gidji JV Project, 80% owned by Miramar, forms a crucial part of the company's portfolio of three projects within Western Australia's esteemed Eastern Goldfields province. This site spans approximately 15 kilometers along the Boorara Shear Zone, an area renowned for its association with numerous gold deposits that extend in both directions. This announcement follows the company's finalization of a binding sale agreement for its Randalls project in October of the previous year, located about 70 kilometers east of Kalgoorlie, WA.
The significant increase in the gold exploration target at Gidji signals a promising future for Miramar Resources and the broader Western Australian gold mining sector. The strategic approach to exploration, coupled with a focus on data-driven decision-making, could unlock substantial value and contribute to the region's economic landscape. This development highlights the continuous effort within the industry to leverage advanced geological understanding and technology to uncover valuable natural resources, reinforcing Western Australia's reputation as a prime location for gold exploration and development.
